Using Blu-ray M-Disk as Backup of Last Resort (smyck.net)

This seems a little over the top to me.

Just use a magnetic hard disk and your data will be fine for many decades if not centuries. You don't need M-Blu Rays (which have very limited capacity anyway). A hard disk is cheap and stores several Terabytes.

You obviously need to store the data in a physically remote place like your shed, car or safe deposit box in case your house burns down.

Never, ever use a SSD if you want your data to be safe for any amount of time. What's worse, SSDs can fail unexpectedly with almost zero chance of data recovery.

Hard drives are way bigger, but M-Disk is more reliable for very long term storage.

I use a 2.5" drive. I find them ideal. But then again my backup footprint isn't double-digit terabytes.

With the decline in quality I am no longer confident my HDDs are actually a save backup strategy.

I have so many photos of vacations and people who I've buried over the years, that I don't want to lose.

So I was thinking about using Blu-ray M-Disks as well, these last couple of months.

100% everything here. That level of tamper evidence should be good enough for the reasonable individual, IMHO.

On the enterprise scale, the question I think everyone should be asking is: Do they have LTO tapes on a shelf? Fundamentally the same issue (but larger), in terms of needing to ensure it's physically separate, and secure, and tamper evident. =)

Anything in the cloud or connected to your network can be hacked. The backup of last resort must be on a shelf.
